PATENT OFFICE CAKE AND SKEIN TREATING SYSTEM Application October 6, 1931, Serial No. 567,317 In Germany November 20, 1930 10 Claims.

This invention relates to a novel washing machine arrangement to be used in the washing and treating of spinning cakes, produced, in the artificial silk industry, by the centrifuge spinning process.

In the production of artificial silk by this process, the threads or filaments, having been extruded into a suitable spinning medium, are led over a guide into a rotating pot. The bodies of thread thus produced are known as cakes. The cakes are then subjected to several chemical treatments such as desulphurizing, copper removal, bleaching, deacidifying, and sizing. These treatments are included in the so-called wet treatmen steps, and may be performed by drip washing, sprinkling or dipping.

It is an object of this invention to provide a Washing and/or treating unit with means which will conduct the cakes of yarn through the unit in such a manner that the various treatments necessary, may be effectively carried out.

It is another object of this invention to provide suitable means whereby the yarn may be changed from the round cake form to skein form.

It is a further object of this invention to provide means whereby the yarn skeins may have their position reversed on the carrier rods thus affording a suitable method by which all of the threads of each skein or cake may be thoroughly 0 subjected to the various treating liquids.

A still further object of this invention is to provide means whereby the carrier rods may be easily secured to the endless transporting belt or chain.

These and other objects of this invention will become more apparent from a perusal of the following description and a study of the drawings in which:

Figure 1 is a diagrammatic View of the treating arrangement;

Figure 2 is a detailed fragmentary view of the unit showing the manner in which the skeins or cakes are mounted on the carrier rods;

Figure 3 is a view showing one method of securing the skein carrier rods to the endless conveyor chain or belt; I

Figure 4 is a view of another method of securingthe skein carrier rods to the endless conveyor 0 chain or belt;

Figure 5 is a detailed view of the endless conveyor chain or belt and showing the mechanism used to reverse the position of the skeins on the carrier rods; and

Figure 6 is a detailed view showmg a second method and mechanism of reversing the position of the skeins on the carrier rods.

Referring now more particularlyto the drawings, there is shown a skein treating unit through which the skeins 1, carried by the carrier rods. or sticks 2, are transported in a zig-zag manner by means of a pair of endless conveyor chains or belts 3. Each chain comprises a plurality of links secured together by means of bolts, 5.

Mounted at spaced intervals on the endless conveyor chains or belts are means whereby the skein carrier rods may be secured or attached thereto. In Figure 3 there is shown one method of attaching these rods to the chains, and comprises a tube 4 having an opening 21, formed therein of such a size as to snugly receive the shank of the bolt. The tubes are s'ufiiciently Wide and deep so that the ends of the carrier rods can be very easily inserted therein. In Figure 4 the bolt itself is provided with an opening 5 in which the end of the carrier rod fits.

The endless conveyor chains or belts are driven by the sprockets 6 and 7 arranged in pairs. The corresponding sprockets are secured to the same drive shaft which passes through the machine in a longitudinal direction. All of the connecting drive shaftsof the individual sprocket pairs maybe driven by any suitable source of power, or only the shafts in the upper part of the unit need be driven.

Between two corresponding upper located sprockets there is installed the cake or skein turning or reversing cylinders 8, as is clearly shown in Figure 5, which are secured in any desired manner to the respective connecting driveshaft. The purpose of these cylinders is to turn the skein or cakes 180 on the carrier rods. The operation of these cylinders is as follows: 'I'heskein 1 supported at 2' by a carrier rod is prevented from swinging freely on the carrier rods by the cylinder 8. With the continuous movement of the conveyor chain the skein will reach the posi-* tion indicated by 1" where the carrier rod' will not be supporting the skein which is held wholly by engagement with the cylinder. When the skein has passed over the cylinder that part of the skein which was against the carrier rod be fore its passage over the cylinder will now be swinging free as indicated at 1". In the right hand part of the Figure 5 the skeins are not turned but are allowed to swing free during their passage 'over the chainwheel as indicated at'1".

In Figure 6 there is shown a modified form of mechanism for'use in reversing the position of the skeins on theca'rrier rods. This mechanism comprises two parallel boards 10 and 11 secured to correspondingly shaped members 10 and 11 of a cylindrical member secured to a shaft 9. These boards are positioned tangentially to the said shaft. During the gradual movement of the chain wheels 6 the rising cakes or skeins are caught flat by one of the boards 10, lifted up and then dropped onto the carrier rod after they have been turned through an angle of 180.

Before the spinning cakes supported by the carrier rods are inserted into the washing or treating machines, they are in a more or less round form 1a, which gradually changes into a skein-like form due to the treating liquids spraying thereagainst or by contact therewith. It has been found that reliance cannot be placed on such methods of changing the shape of the cake, and, therefore, mechanism has been provided which will mechanically change the cakes into a uniform skein like shape prior to the wet treatment and particularly before they have been subjected to the turning arrangement.

This mechanism as clearly shown by Figures 1, 2 and 5 comprises a pair of rods 12 and 13 located .on either side of the conveyor chains or belts. Positioned above this pair is a second pair 14 and 15. The cakes 1a, supported on the carrier rods, and still having their round form, pass first upon the movement of the conveyor chain or belt between the first pair of rods 12 and 13 by means of which they are partially compressed into skein form as shown at lb. Further movement of the conveyor chain or belt moves the partially compressed cakes through the upper pair of rods which imparts to them the final skein form 10. It is obvious, however, that this compression of the cakes into skein form may be accomplished by using only one pair of rods, but the use of two pairs of rods, located as described, prevents or aids in the prevention of any injury to the threads making up the cake.

At the places where the skeins are placed in and removed from the machine there are installed vertically disposed partitions 16 and 17, made of glass or other suitable material, which prevents the workers from being splashed with the treating liquid.

The treating liquids are brought into contact with the skeins by means of suitable spraying nozzles 18 and 19 located at convenient points in the system. Containers 20 are positioned below the skeins to collect the used treating liquids. The spraying nozzles can be so arranged on the extension over the cakes that the treating liquids may fall from one series of cakes to another, or the spinning cakes can be dipped in troughs containing treating liquids placed below the turning points of the endless conveyor.

If one and the same chain-batch is to be passed through all the respective treating baths in sequence, care has to be taken that the materials of which the parts of the device are made are equally resistant to the attacks of the different baths.

It will be readily appreciated that by the above description, arrangement is provided for a simple and efficient means for handling the skeins while subjecting them to the desired wet treatment.

While the present invention is more particularly adapted to handle cakes formed .by the potspinning process during the wet treatment thereof, it is not limited to such use but may be employed for handling skeins of yarn during the wet treatment thereof which may be produced by methods other than the pot-spinning process.

While there has been disclosed in this specification one or more forms in which the invention may be embodied it is to be understood that they are shown for the purpose of illustration only, and that the invention is not to be limited to the specific disclosure but may be modified and embodied in various other forms without departing from its spirit.
